Abstract

A brightness adjustment system of a surround view system may include at least two adjacent image sensors providing images covering different fields of view of a user's surroundings. A first image sensor and a second image sensor of the at least two image sensors may be configured to capture images using an adjustable exposure time. An exposure time control unit may be provided that may be configured to determine, for the at least two adjacent image sensors, one or more brightness parameters from image data provided by the image sensors. The exposure time control unit may be further configured to control the exposure times of the image sensors such that the brightness parameter(s) determined for the first image sensor at least approximately matches one or more corresponding brightness parameters determined for the second image sensor.
